Ok, I have hatched 7 out of 30 shipped eggs in the past. Now I am about to try again, will be setting 24 eggs tomorrow, and yes they are shipped eggs. I received 1 dozen yesterday and the other which was supposed to be here yesterday should get here today. I am going to wait and set them all together after allowing the 2nd dozen to sit for 24 hours. I have tried on the first batch keeping humidity set at 50% and temp stable at 100, then at lockdown bumped humidity to 60%.. only 3 hatched out of that. Then the next I tried humidity at 30-40% and bumped it to 60% at lockdown, 4 hatched. These are Marans eggs and very hard to candle. Once again Marans eggs.... so what is the best humidity settings or am I in the ballpark? ALso, how the heck can you candle dark eggs? I have tried highpower LED flashlights and can't see anything. I have read and re-read the candling sticky thread. Appreciate any help as I would really like to make sure its not something I am doing to get these poor hatch rates.
